互联网时代的加速演进下,我们进入了大信息和大数据时代。从某一天起,我们打开各类新闻和资讯类 App,标题党充斥和断章取义者遍地已是常态,爆炸的海量内容和基于人性的上瘾算法,更让时间在手指向上向下向左向右的滑动和刷新中匆匆然流逝。 于是,在入睡时,放下或掉下手机,你好像知道了好多,却又好像什么也没留下,碎片化的信息和琐碎的知识,吞噬了生命中的大量时间。有一刻我们有所觉悟,好像除了视力的下降和脸上斑纹的增多,其余无所获。 更有时,当别人在身边讨论这样那样的话题,竟然我们一头雾水,我们不经意间错过了一些大事而失去了话题参与性。 蹉跎中和迷惑中回头有思,每个人都是自己命运的最大 Boss,而作为自己的老板,我们需要一个小秘书 —— 每天早上 5 分钟提供一份简报,摘要概述 24 小时内、一周内、一年内的大事件…… 国内国际,微博知乎,新闻联播节目概要,科技财经生活娱乐汽车…… 这便有了「要知」。 信息无穷尽,要知要知的。 知所要,知重要 - 要知要知的。 重要,必要,需要 - 要知要知的。 我们要知道那些要知道的,这便是「要知」的名字由来。
